A bed includes components to control pressure of a sleep surface, for example based on sleep position and sleep stages of a user. In some embodiments target pressures for the sleep surface are iteratively adjusted over multiple sleep sessions so to achieve improvements in sleep states and/or sleep quality for the user.

A bed has a mattress. A sensor system is configured to sense at least one physical phenomenon through a sleep session. A controller may include at least one processor and memory, the controller configured to receive, through the sleep session, the sensor data; select, from a plurality of optional algorithms, a selected algorithm based on at least one of the sensor data, user input, and checking a clock, where the optional algorithms include (i) a state-based algorithm and (ii) a schedule-based algorithm; update, through the sleep session, using the selected algorithm, a current sleep state of the sleeper; track the sleep session based on the update of the current sleep state of the sleeper through the sleep session; update, through the sleep session, using the tracking of the sleep session, a target environmental-parameter; and send, through the sleep session, automation instructions to an environmental controller.

Described herein are devices, systems, and methods relating to making individuals comfortable when in contact with surfaces (e.g., seats and beds) including preventing pressure injuries on subjects. In embodiments, disclosed herein are pressure injury prevention systems comprising actuator assemblies that can simultaneously provide immersion and offloading of pressure while allowing a subject to retain balance. In other embodiments, moisture control devices and/or sensing networks can be used in conjunction with said actuator assemblies to prevent pressure injuries in a subject in need thereof. In embodiments, also described herein are computing devices and applications that alert a manual intervention or trigger an automated intervention between the individual and the intervention surface based on a risk determination. Such interventions can send instructions to the system to relieve pressure and/or moisture at one or more interface locations on the interface surface between the system and a subject according to a set of rules based on a predetermined profile, data collected continuously in real time, or both.

Introduced are methods and systems for an adjustable bed device configured to: gather biological signals associated with multiple users, such as heart rate, breathing rate, or temperature; analyze the gathered human biological signals; and heat or cool a bed based on the analysis.

Historical sleep metrics are accessed. Historical sensor data is accessed. Incidences of low quality sleep experienced by the user are identified. Particular environmental conditions that affected the user during the incidences of low quality sleep are identified. A corrective plan that specifies a change to an environmental control system to reduce the particular environmental conditions is created. The behavior of the environmental control system is modified such that the environmental control system reduces the particular environmental conditions when the user sleeps in the bed.

A modular multi-zone mattress and related method of design for which a plurality of mattress modules are adjoined to define a sleep surface having a variable deformability. A number of the mattress modules and a deformability of each mattress module are tailored to a unique body shape and weight distribution of a mattress user to provide at least one of an optimized body posture and an optimized contact pressure distribution over the sleep surface. Pressure factors include a weight and a morphologic profile of the mattress user, and optionally, a sleep position of the mattress user.

A system for simultaneously measuring the indentation hardness properties, span properties, and resilience properties of a mattress includes a first indentation means and a second indentation means, and means for urging the first indentation means and the second indentation means into the mattress with a predetermined force, and also includes laser means for projecting a laser line configured to map, preferably by photographic triangulation, the amplitude, shape, and time-dependency of the resultant deflection of the mattress surface between the first indentation means and the second indentation means. A method for simultaneously measuring the indentation hardness properties, span properties, and resilience properties of a mattress is also provided.

The present invention discloses a multifunctional motion simulation bed which has multiple segments and simulates preprogrammed motions. The segments are articulately connected to form a motion platform. In one embodiment, the segments are disposed above a base. Actuators are mounted on the base and pivotally coupled with the base and the segments. A microprocessor drives the actuators individually and causes the motion platform to simulate motions. In another embodiment, the segments are disposed above a frame which is arranged above a base. One segment is fixed on the frame. Some actuators are pivotally coupled with the frame and some of the segments. Other actuators are pivotally coupled with the frame and the base. A microprocessor drives the actuators individually and causes the frame and motion platform to simulate motions.

A bed includes a mattress set on which a user's body is placed, an adjustable bedframe to adjust a position or orientation of the mattress set for various sitting and sleeping positions, and a dryer to dry the mattress set. The dryer includes a fan, a filter, and a heater to discharge filtered hot air toward the dryer to reduce mildew and mites. A humidity sensing sheet may be provided to sense a humidity level at different regions or areas of the bed, and the dryer may be controlled to supply hot air to regions of the bed having a higher humidity level than a predetermined humidity level or humidity range.

An acquisition apparatus for acquiring physiological data of an individual, configured to be installed in a bed frame, with an acquisition portion which includes a sensor intended to capture mechanical waves transiting in the bed frame, a support device including one or more rigid panels, the support device being configured to rest on bed frame elements which may be discontinuous for example slats, so that the support device is interposed between the bed frame elements and the sensor, and may provide a substantially continuous support to the sensor receiving the mechanical waves generated by the individual through the bedding, if necessary with folding zones between panels.
